hmm i think the way the light was positioned or how this shot was exposed made you lose a lot of contrast in the face. i see you might have been trying to go for the high key effect. but the lighting sort of takes away all shadows which take away the 3d ness of the shot
To my untrained eye the first thing I saw was how in focus her eyes are and how soft or out of focus the rest of her is. I like the overall color though.
A couple of suggestions I would give for this one. The overall feel, while I'm sure is meant to be soft, also feels out of focus to me. I think a big part of that is from the large fall of hair on her shoulder that is all out of focus.
The eyes also seem dark. The muted tones can work, but I would still like to see more lightness in the whites of the eyes. As it is, the whites almost match the skin tone, which really loses the focus on them. The muted tones also seem to make the bottom rim of the eyes kinda pink, like she's been crying or something.
Just one woman's opinion but I hope this is helpful.
Very nice portrait, but it's too obvious the eye didn't get the same post-processing than the rest of the photo, and I think it's kind of disturbing ....
